Hi Baz, thanks for that , it looks like a 1" lamination popular for small transformers at the time and smaller than the one I was looking at.

Are the lams gapped, it looks a bit like it from the picture and it could also be using large and small E lams, which would be difficult to get, but not to rewind.
There should be no DC in the primary winding, but there may be in the secondary winding, which would require a gap.
